Topographic Analysis of Subsurface Crack Initation Behavior of Beta-Type Titanium Alloy
抄録
The subsurface fatigue crack initiation and propagation behavior of beta-type titanium alloy was investigated by the reconstruction of fracture surface and computer simulation. The FRASTA (fracture surface topographic analysis) technique which reconstructs the fracture process form the three-dimensional topographies of conjugate fracture surface was applied to the fatigue fracture of Ti-15V-3Cr-3Sn-3Al alloy. From the result, it was found that the subsurface crack initiation and growth process could be reappeared clearly by the FRASTA method.
